Application filed 3111:, 16, 1913. Serial No. 729,692.

of llion, the county of Herkimer and State of New York, have inventedcertain new and useful Improrbments in T ype- Writing Machines, of whichhe following is a specification.

My invention relates to typewriting g, machines and also to othermachines in which paper is used after the fashion of typewritingmachines, such, for example, some forms of adding machines.

My invention has for its principal. object to provide improved paperfeed mechanism for such machines.

One of the objects had in mind in the present invention has been toprovide paper feed mechanism of inexpensive construction and yetthoroughly good and efficient.

To the above and. other ends my invention consists in certain featuresof construction and combinations and arrangements of parts. all of-whichwill be fully set forth herein and particularly pointed out in theclaims.

In the accompanying drawin s, Figures 1 and 2 are vertical fore and aftsectional views through the carriage of a typewriting machine, with myinvention embodied therein, both; of said figures being on an enlargedscale. in Fig. 1 the parts are shown in normal positions (and in Fig. 2in releasing positions. Fig. 3 is a front elevation, and i ig. 41. is atop plan view of said carriage. I

in the drawings parts have been omitted and parts have been shown insection or broken away as found convenient.

As far as my present invention is con- ;erned the typewriting or othermachine can, to most of its features, be of any suitable sort. in thepresent instance 1 have shown'in Fig. 1 part of stationary rail 1, whichrail has its forward and rear edges grooved to coiipcrate *ithantifriction balls 3, which in turn support grooved rails 3 constitutingpart of a typewriter carriage having end pieces or brackets 4. Sta-- 9tionary and movable rail construction and the ball bearings therefor,such as are sought to he represented in the present case, are more fullyshown in the patent to Alex ancler T. Brown No; 935,77 6, dated October5,1909, although it will of-course be under stood that as far as gayinvention is concerned these parts may be otherwise constructed, andindeed it is not essential to my invention that the parts hereinafterdescribed be on a carriage at all. Said caras here shown, constitutes aplaten frame in which a. cylindrical platen 5 is mounted by means of itsaxle 6, which axle is journaled in the end brackets 4. Said platen maybe provided with the usual finger wheels or other suitable means forturning it, and it is here shown equipped with a line space wheel '7 tobe operated by any suitable pawl or other inechanisi 1 after theordinary fashion of these machines. In the particular machine shown inthe drawings, type bars 8 (Fip. 1) are so mounted to strike againstthefront face of the platen 5, as shown.

In the platen frame above'described, I pivot yoke frame comprising aloft-hand arm 10, a righthand arm 11 and across rod or bar 12 connectingthe upper parts of said arms 10 and 11 below and in fro of the center ofthe platen. arms 10 and 11 is provided at its lower end with a stud ortrunnion 13 suitably pivoted in the end brackets 4-, as indicated inFigs. 1 and 3. The rod 12 is rigidly secured at its ends to the arms 10and 11 so thaou hen one of said arms turns about its pivot 13---:theother arm is caused to turn also.

A scale plate 14 is shown situated at a. suitable distance below thefront face of the platen 5, said scale plate consisting of a str'p ofmetal having its ends secured by screws 15 to 1G bent off from the arms10 and i1.

It will be perceived that the rod 12 is so mounted that when the yokeframe of which it forum a part is rocked about its pivots 13, said barmoves forward and somewhat downward. I

1', paper apron or deflector 17 extends longitudinally of the platen andis formed concave on its upper surface and is so disposed that normallyits forward part is pressed against the platen, as shown in Fig. 1. At

sch of its ends this paper apron has bent off therefrom an car 18 whichis formed with an open slot that straddles the end of the rod 12 towhich the paper apron is thereby detachably pivoted. As shown in Fig.3these cars come just inside the arms 10 and 11. At its rear edge and ateach Each of the I in the bi'sc 'efis 4.
